Manual:Hooks/PrefixSearchBackend

This deprecated feature should no longer be used, but is still available for reasons of backwards compatibility.
This feature was deprecated in version 1.27.0. Instead, we recommend overriding SearchEngine::completionSearchBackend and other completion function as needed. See: mailarchive:wikitech-l/2016-February/084776.html
